CORNER MARKER FOR LAND SURVEYS.

Application filed March 11, 1927. Serial No. 174,552.

, 6 reference to weather-resistance, visibility and adaptability to beso anchored as'to resist;

, removal by the careless or malicious, whereby the permanence of landsurveys is secured to a degree not before possible, save at prohibitoryexpense.

With these ends in view, my invention consists in a corner marker havingcertain details of construction as will be hereinafter described andpointed out in the claim.

In the accompanying drawings:

Fig. 1 is a view in perspective of a corner marker constructed inaccordance with my invention;

Fig. 2 is a "view showing the same as installed so as to form what isknown by surveyors as a monument;

Fig. 3 is another form of my corner marker provided in this instancewith a shield-shaped location-head and with a cast-cement base; and

Fig. 4 is a broken view of the upper end of a rod of a marker providedwith an integral location-head.

In carrying out my invention as shown in Figs. 1 and 2, the markerconsists of an upright rod 5 preferably made of a superior grade ofSwedish iron known for its quality of resisting weather, bent at itslower H end to form a substantially-circular anchor 6 located in a planeat a right angle to the vertical plane of the rod, though it is notessential that this anchor should be substantially circular in form, theonly requirement being that it shall lie in a horizontal plane and befitted to be held down by a superimposed load of stones, gravel, ordirt. At its upper end, the rod 5 is provided with a disk likelocation-head 7 secured to it by a rivet 8, or in any other approvedmanner, the upper face of this head being provided with lettering orfigures (not shown), or other indicia of ownership and relativelocation, either cast or cut into it or etched or painted upon it, asmaybe found convenient.

In Fig. 2 I have illustrated a mode of installation consisting indigging a hole 9 0n the bottom of which the anchor 6 rests. Small stones10 are then piled upon the anchor and about the lower end of the rod,around the upper portion of which stones 11 are piled, the extreme upperend of the rod, with its location-head 7 rising above them. It will beclear that when so installed, the marker cannot be removed, save byconsiderable efiiort and is likely to be left undisturbed.

In the form of marker shown by Fig. 3, the upper end of the rod 5 isfurnished with a shield-shaped location-head 12 permanently secured by arivet 13 or otherwise and located in the vertical plane- Thislocationhead will be provided with initials or figures accordingto'circumstances and secures a high degree of visibility, particularlywhen galvanized. In this construction, the anchor 6, at the lower end ofthe rod, has cast upon it a heavy base 14 of concrete, which securesadditional permanence of installation at somewhat greater expense. Thecorner marker shown by Fig. 3 is designed to be installed in the samemanner as illustrated in Fig. 2.

In Fig. 4 the rod or post 5 is flattened to form an integallocation-head 15 of smaller area than the location-heads 7 or 12 andhaving, therefore, less visibility but answering all purposes and, beingintegral with the rod, impossible to remove therefrom and also cheaperto produce.

By preference, the rod and location-head will be galvanized forincreasing their visibility and, to some extent, their resistance toweather, though this is not considered essential. I

By means of my improved corner marker, the landowner, who has gone tothe expense of a survey of his holding, whatever its size and character,may give permanence to his established lines, making further surveyscomparatively easy and largely eliminating the boundary disputes sovexatious to all land-owners.

I claim:

As a new article of manufacture, a selfcontained corner-marker forland-surveys, comprising a metal rod, a location-head made independentof the said rod, permanently attached to the upper end thereof andoverhanging the same so as to show a relativelylarge display-surface, ananchor formed integral with the lower end of the rod, arranged I in aplane at a right angle thereto and substantially concentric therewithand comprising an arm bent at a right angle to the lower end of the rodand having a circular "extension, and a cement base initally cast aroundthe said anchor which is embedded in it and standing in a plane at aright angle to the plane of the rod, whereby, when a load is imposedupon such base, the rod is maintained in a vertical position. 10 Intestimony whereof, I have signed this specification.

GEORGE A. CRQMIE.
